Augmented reality-based space positioning method and device

Abstract

The invention relates to the field of space positioning, and discloses an augmented reality-based space positioning method and device. The augmented reality-based space positioning method comprises the following steps of: obtaining a deviation angle of a double-camera coordinate system relative to a world coordinate system, wherein the world coordinate system is a coordinate system established by taking a known target position of a positioning photosphere as a reference coordinate; obtaining a practical position of the positioning photosphere in the world coordinate system; calculating coordinate values, in the world coordinate system, of two cameras according to the deviation angle and the practical position and target position of the positioning photosphere; and determining a position, in the world coordinate system, of a virtual object in a virtual space according to the coordinate values, in the world coordinate system, of the two cameras. Compared with the prior art, the method and device are capable of ensuring the position superposition of virtual objects and positioning photospheres so that virtual objects in virtual scenes can be tightly combined with real objects.

Description

technical field [0001] The present invention relates to the field of space positioning, in particular to a space positioning method and device based on augmented reality. Background technique [0002] AR (AR is the abbreviation of Augmented Reality, Chinese interpretation is augmented reality technology or augmented reality) is a technology that calculates the position and angle of camera images in real time and adds corresponding images, videos, and 3D models. The goal of this technology is Put the virtual world on the screen and interact with the real world. With the improvement of the computing power of the portable electronic product CPU (CPU is the abbreviation of Central Processing Unit, the Chinese interpretation is the central processing unit), it is expected that the use of augmented reality will become more and more extensive. [0003] In the prior art, the AR head-mounted device used by the user usually adopts the Inside-Out solution to locate the virtual object....

Problems solved by technology

[0004] However, the inventors of the present application found in the process of implementing the present invention that there are still the following technical defects in the prior art: when the dual camera device is displaced or rotated relative to the positioning photosphere, the objects in the virtual scene cannot be aligned with the positioning The position of the light sphere coincides, so that the objects in the virtual scene cannot be closely combined with the objects in the real scene
